named for many years : it is said to have come from Singapore ; but 

 that probably was only the port of transit. It may be only a small 

 pale local variety of T. kanchil. 



Six specimens, adult, all exactly similar ; one young. 



Sus ? 



Hab. Camboja. 



There are two lower tusks of this genus in the collection, indicating 

 the existence of a species of the genus ; one is very large and thick, 

 the other is elongate and slender. They may be the tusks of the 

 two sexes. 



Manis pentadactyla, Linn. 



Hab. Camboja. 



Two specimens, adult and half-grown. 



Reptilia. 



Testudo elongata. Gray. 



One specimen, half-grown. 



The shields are yellow, with an irregular black ring round the 

 areola ; the disk of the areola is sometimes varied with a few round- 

 ish black spots ; the sternal shields are yellow, with an irregular 

 square subcentral blotch covering part of the areola.

 t. xxi. 



Hah. Siam and Camboja. 



Two specimens, one adult, other young. 



The adult is nearly twice as large as the specimen first described ; 

 the three keels are distinct, but very blunt, and the vertebral shields 

 are oblong, transverse, but rounded at the angles ; the margin of the 

 shell is yellow ; the under side yellow, with a more or less large black 

 blotch on each shield. 



The young shell is brown, with a narrow, pale-yellow margin ; the 

 keels are very distinct ; the central one is very broad, and wider on the 

 hinder parts of each shield; the lateral keel ends with the third costal 

 plate, and is at the end bent in towards the central line ; the under- 

 side is dark brown, with a white streak down the centre, and a 

 white streak on the margin ; and on the keel, which separates the 

 flat parts of the sternum from the shelving part of the sides, that 

 shelving part is high, much higher than in the adult shell. 



Geoemyda spinosa. Gray, P. Z. S. 1834. 



Hab. Camboja. 



Three specimens in different ages, from young to nearly adult. 

 They are all marked with radiating brown lines on each of the sternal 

 and the under side of the marginal shields, which are vridest in the 

 youngest and narrowest in the most adult specimens. The older 

 specimen alone has these lines on the dorsal and upper side of the
